    Abstract: A camera has two distinct image sensor arrays. The image sensor arrays are at least one of different types and different resolutions. The image sensor arrays have different dynamic ranges such that one of the image sensor arrays is a high dynamic range image sensor array configured to capture a wider range of light intensity than the other of the image sensor arrays. The camera has an imaging mechanism configured to combine information collected by each of the image sensor arrays to produce a high dynamic range image. The image sensor arrays include one low resolution image sensor array having a high dynamic range, and one high resolution image sensor array having a normal dynamic range smaller than the high dynamic range wherein luminance values within the normal dynamic range represent a subset of luminance values within the high dynamic range.

    Abstract: Apparatus and methods are provided that employ one or more of a variety of techniques for reducing the time required to display high resolution images on a high dynamic range display having a light source layer and a display layer. In one technique, the image resolution is reduced, an effective luminance pattern is determined for the reduced resolution image, and the resolution of the effective luminance pattern is then increased to the resolution of the display layer. In another technique, the light source layer's point spread function is decomposed into a plurality of components, and an effective luminance pattern is determined for each component. The effective luminance patterns are then combined to produce a total effective luminance pattern. Additional image display time reduction techniques are provided.

    Abstract: Dual modulator displays are disclosed incorporating a phosphorescent plate interposed in the optical path between a light source modulation layer and a display modulation layer. Spatially modulated light output from the light source modulation layer impinges on the phosphorescent plate and excites corresponding regions of the phosphorescent plate which in turn emit light having different spectral characteristics than the light output from the light source modulation layer. Light emitted from the phosphorescent plate is received and further modulated by the display modulation layer to provide the ultimate display output.
